WINDOW-SCREEN.

Patented Dec. 1'8, 1906.

Application iiled October 6, 1905. Serial No. 281,625.

To all. who/1L it may concern:

Be it known that I, RICHARD KERsEY, a citizen of the United States,residing at Lexington, in the county of Fayette and State of Kentucky,have invented a new and useful Vindow-Screen, of which the following isa specification.

The invention relates to improvements in window-screens,

The object of the present invention is to improve the construction ofwindow-screens, and to provide a simple and comparatively inexpensiveone adapted to be readily applied with slight change to the top andbottom of a window and connected with the sashes thereof for screeningthe top and bottom of a window when the sashes are open.

A further object of the invention is to provide a window-screen of thischaracter adapted to effectually exclude flies or other insects andcapable of automatically rewinding itself when a sash is closed and ofrelieving the sash of the tension of the spring for rewinding thescreen, so that the spring will not close an evenly-balanced sash.

Another object of the invention is to provide means for preventingflexible screen material, such as mosquito netting and the like, frombeing worn through its attachment to a sa'sh. I

lith these and other objects in view the invention consists in theconstruction and novel combination and arrangement of parts hereinafterfully described, illustrated in the accompanying drawings, and pointedout in the claims hereto appended, it being understood that variouschanges in the form, proportion, size, and minor details of constructionwithin the scope of the claims may be resorted to without departing fromthe spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure 1 is an elevation of a window provided `withupper and lower screens constructed in accordance withthis invention.Fig. 2 is a vertical sectionalview of the same, taken substantially onthe line 2 2 of Fig. 1. Fig. 3 is a perspective view of the lowerscreen, showing the same detached. Fig. 4L is an enlarged detailhorizontal sectional view of one side of the screen. Fig. 5 is a detailperspective view of a portion of the screen, showing one of the metallicloops. Fig. 6 is an enlarged detail sectional view taken substantiallyon the line 6 6 of Fig. 7 and illustrating the manner of mounting oneend of the spring-actuated roller. Fig. 7 is a-detail sectional viewtaken substantially on the line 7 7 of Fig. 6. Fig. 8 is a detailsectional view illustrating the manner of mounting the other end oftheroller.

Like numerals of reference designate corresponding parts in all theiigures of the drawings.

1 designates the frame of the Windowscreen, which, as illustrated inFigs. 1 and 2 of the drawings, is adapted to be applied at both the topand bottom of a window, and when applied at the top it is located onvthe exterior of the window and on the interior when arranged at thebottom of the window. The frame 1 is substantially U-shaped and iscomposed of vertical sides 2 and a connecting transverse portion 3,which is in the form of a casing and which houses a spring-actuatedroller 4. The sides 2 are substantially vL-shaped in horizontal or crosssection to it snugly a window frame or casing 5. The spring-actuatedroller on which the flexible screen material 6'is wound is similar inconstruction to the spring-actuated roller of an 'ordinary window-shade,and its round jourfrom a slot or opening 14 of the transverse v casingand receiving iiat longitudinal guide bars 15, on which slide loops 16of the flexible screen 6. The flexible screen 6 may be made ofmosquito-netting or any other suitable screen material, and the loops16, which are approximately U-shaped, extend hori- Zontally from theends of a slide 17, consist* ingof a cross bar or member extendingentirely across the frame and provided With means for detachablyconnecting it to a window-sash. The slide 17, which forms a crosse bar,preferably consists of intermediate and side pieces, the loops 16 beingsecured to the intermediate piece, as clearlyshown in Fig.

IOO

4. The outer transverse edge of the screen material is also securedbetween two of the pieces of the slide 17, and the side edges of theflexible screen are passed around the guide-bars and stitched orotherwise secured to form hems or casings 18, whereby they are slidablyconnected with the said. guide-bars. The unrolled portion of the screenis connected at each side throughout its entire length with the bars bythe hems or casings. These guide-bars, which terminate shortvof thebottom of the casing7 have enlarged upper ends, which are securedbetween the bars or members of the sides 2. These bars or members, whichare spaced apart to provide the vertical openings 13, are preferablyconnected at the top by substantially L-shaped cap-pieces 3a. The loops16 are each composed of two plates `or pieces which receive the fiexiblescreen between them, as clearly shown in Fig. 5 of the drawings. rl`heslide 17, which is provided at the outer faces of the sides 2 of theframe 1 with extensions 19, is detachably secured to the window-sash bymeans of catches 20. The extensions 19 overlap the sides 2 of the frameand are adapted to slide thereon. The catches 20, which are preferablyin the form of hooks, engage the bottom bar 21 of the lower sash 22 orthe upper bar 23 of the upper sash 24 and are provided with eyes 24a,which are linked into eyes 25 of the slide 17. By this construction theflexible screen material is prevented from being worn or otherwiseinjured through its attachment to the sashes of the window.

When either of the sashes of the window is opened, the flexible screenconnected with such sash is unwound from its roller, and when the sashis closed the fiexible screen is automatically rewound on the roller bythe spring of the latter. In order to relieve the sashes of the tensionof the spring and prevent the latter from closing, an evenly-balancedsash, a ratchet-wheel 26, and a dog 27 are provided. The ratchet-wheelis mounted on the roller 4 at the round journal 7, and the dog, which isin the form of a lever, is pivoted at its inner end 28, and its outerend extends through a slot 29 of the outer wall of the casing 3. Thecasing at the bottom of the window is provided at the outer side of theslot 29 with a shoulder 30, adapted to support the pivoted dog 27 out ofengagement with the ratchet to permit the springactuated roller toautomatically wind up the liexible screen as the sash is closed. The dogof the upper window-screen is adapted to rest upon the ratchet-wheel,and it may be omitted, if desired, or any suitable means may be employedfor lifting the upper dog out of engagement with the upper ratchetwheel.When the catches are disengaged from the sashes, the screens will remainwound on the spring-actuated roller, andthe latter will automaticallyrewind the flexible screens should the same be detached from the sashesand the pawls or dogs disengaged from the ratchet-wheels. l

By slidably connecting the side edges of the screen material with thevertical guides of the sides of the frame 1 insects are effectuallyprevented from passing around the side edges of the screen, and a guardconsisting of a strip 31 is preferably mounted on the upper sash at thebottom thereof to close the space between the sashes when the same arepartly open, as illustrated in Fig. 2 of the drawings, to prevent anyinsects from crawling upward between the sashes. This strip ispreferably constructed of rubber or other yieldable material but it maybe constructed of wood, metal, or other inelastic material. Thescreen-frame and roller may be made of either wood or metal.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. A window-screen, comprising a frame provided with vertical sides andhaving a connecting portion, a flexible screen provided with a rollermounted within the connecting portion, a slide movable on the sides ofthe frame and attached to the flexible screen and arranged to litagainst one edge of the end bar of a sash, and a hook-shaped catchhinged to the slide and arranged to engage the end bar of the sash atthe edge opposite that against which the slide fits.
